COMPOUND VE SSEL.

Specification of Letters Patent.

Patented July 13, 1909.

Applicationfiled May 13, 1908. Serial No. 432,693.

vide an improved compound vessel, in w ich the severa independentreceptacles will be securely maintained sealed, and in which theclosures of said receptacle will be efficiently shielded againstaccidental displacement.

A further object of my invention is to arovide an improved compoundvessel, in w ich the severa ceptacles will be ositioned on the exteriorof the vessel; there y enabling each receptacle to be openedindependently, and preventing the contents of any receptacle from comingin contact with the closures of other receptacles.

In the accompanying drawings forming a part of this application and inwhich simiar reference symbols indicate corresponding parts in theseveral views-Figurc 1 1s a central vertical section'illustrating oneembodiment of my invention; and Fig. 2 is a central vertical sectionillustrating a modified construction.

- Referring especially to- Fig. 1 of the draw ings, 1 indicates mainreceptacle, which is preferably cylindrical and formed of any suitablematerial, such as tinor sheet metal. For convenience in packing andstoring, the receptacle is rovided witha flat bottom 2 and to 3. he flatto 3 is provided with a contra opening, from the periphery of which athreaded cylindrical flan e 4 extends within the receptacle. The cyindrical flange 4 braces the flat top 3 along the periphery of thecentral opening therein, and provides great strength and rigidity tosaid flat top. It will be notedthat the flange/42 is supported only atits upper end, from which it extends freel within the rece tacle;thereby per-- mittlng sufficient yielding of said flan e to accommodateany irregularities, or sight distortions, occurring in the threadedpeclosures of the independent reriphery 5 of the cylindrical capengaging said flange. p

The cylindrical cap has an open top, from which an annular flange 6extends radially for engaging the flat top 3 of the receptacle tosecurely seal the latter. The engagement of the flange 6 with the top ofthe receptacle produces a frictional resistance tending to preventaccidental loosening of the cap. Further, the flange 6 lies snuglyagainst the flat top 3 in a position which efficiently shields it frombeing accidentally struck or displaced. The annular flange 6 is providedwith notches 7 to provide convenlent means for engaging said flange inscrewing the cap to osition. An auxiliary receptacle 8 extends rom theflat base 9 of the cap, and. is rovided with suitable securing means,suc as threads 10 at its upper portion. An auxiliary cap is providedwith a threaded portion 11 for engaging the threads 10, and with anannular flange 12 extending radially for engagement with the flat base 9"to se curely seal the auxiliary receptacle. The flange 12 carries anaxially extending flange 13, provided with notches 14 for convenientengagement in screwing the auxiliary cap to poslt on.

From the above description it will be understood that my inventionrovides an in1- proved construction in whic the severalinde endentreceptacles of a compound vessel w'l be securely maintained sealed, andin which the closures of said several receptacles will be locatedexterior of the vessel and efficiently shielded against accidentaldisplace-- ment. I

Fig. 2 illustrates a modified construction, comprising a main receptacle15 provided with a flat top 16 having a central opening surrounded by aheading 17. An auxiliary receptacle 18 is provided with an annularflange 19 against which is seated a suitable packing ring 20 forengagement with the eading 17. A cap closure 21 threadingly en ages themain receptacle at 22, and is provi ed with a central convex portion 23for engaging the top edge of the auxiliary rece tacle 18 to securelyclose the latter. en the cap closure 21 is screwed tightly in osition,the convex portion 23 thereof will he forced against the top edge of theauxiliary rece tacle thereby securely closing said rece tac e andpressing the packing ring 20 fir y against the beading 17 to seal themain receptacle 15. This provides a very simple and durable form oi?compound vessel, capable of containing separately independentsubstances. 7

My invention is ada ted for use in all cases where it is desire tomaintain'different substances distinctly separated. It is.

especially adapted for convenient use as an artist's box, where it isfrequently desirable to carry the dry colors and varnish separately, inorder that they may be mixed in the proper proportion when required foruse.

I have illustrated and described a preferred and satisfactorconstruction, but, ohviously, changes cou d be made within the spiritand scope of my invention.

Having thus described my invention, what I desire to secure by LettersPatent is In a compound vessel, the combination of a main receptacleprovided with a flat top and a threaded cylindrical flange extendinginwardly therefrom, a screw cap fitting within said threaded flange andprovided with an annular base and an external flange for frictionallyenga ing the top of said main receptacle, an auxiliary rece tacledependent from the annular base of sai cap, and a screw closure for saidauxiliary receptacle provided with an external flange for engaging thebase of said cap and a notched rim extending upwardly from said flangeof less length than said cap, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.
